Title: Operating system and data base having an access structure formed by a plurality of tables
Inventor: CHONG DANIEL T
IPC: G06N5/04
Filed: 1990-09-04
Abstract: A programmable computer which operates by executing rules, each including a rule name, and optionally: input parameters, a set of conditions, a set of actions associated with each condition, and a set of exception handlers. A condition is a logical expression which evaluates to a true or false boolean value, while an action is an executable statement. An exception handler contains executable statements. The computer includes text entry and display means for programming of rules. A rule is displayed with each condition and each action having a row of text. The computer generates a yes/no quadrant into which a programmer may enter sequence numbers, to associate ordered sets of actions with individual conditions. Sequence numbers may be entered not associated with any condition, to define a set of default actions. Upon entering a rule, the computer sequentially evaluates the rule's conditions. Upon a condition evaluating to true, the computer executes the set of actions associated with that condition, then exits the rule. If the rule contains no conditions or none evaluates to true, the set of default actions will be executed, and the rule exited. If, during execution of the rule, the computer detects an exception event, such as a missing datum or other execution error, the computer passes to the rule the name of the detected exception event. If the rule contains an exception handler bearing the same name, the computer will execute the statements within that exception handler.

IPC: B01F23/10
Filed: 1998-04-20
Abstract: A novel injector/reactor apparatus and an efficient process for the partial oxidation of light hydrocarbon gases, such as methane, to convert such gases to useful synthesis gas for recovery and/or subsequent hydrocarbon synthesis.  Sources of a light hydrocarbon gas, such as methane (23), and oxygen or an oxygen-containing gas (22) are preheated and pressurized and injected through an injector means at high velocity into admixture with each other in the desired relating proportions, at a plurality of mixing nozzles which are open to the partial oxidation zone of a reactor and are uniformly-spaced over the face of the injector means, to form a gaseous premix having a pressure drop through the injector. The gasous premix is injected in a time period which is less than 5 milliseconds, preferably at a velocity between about 25 to 1000 feet/second, into a partial oxidation reaction zone so that the gaseous premix reacts therein, to reduce the amounts of CO2, H2O and heat produced by the partial oxidation reaction and form, cool and recover a useful syngas.

Patent CA-2292429-A1 (CA)
Inventor: REITZ DONALD D
IPC: E21B43/12
Filed: 1998-06-17
Abstract: A novel apparatus and method for producing oil and natural gas from an oil well in the later stages of the well's lifetime. The apparatus includes a one-way valve located at the bottom of the conventional production tubing and a string of macaroni tubing inserted inside of the production tubing. The three chambers defined by the casing, the production tubing, and the macaroni tubing, are connectable to either the suction or discharge manifolds of the apparatus, which are in turn connectable to a compressor. With the valves manipulated in the appropriate fashion by the controller, pressure differentials can be created in the down-hole region of the well to force oil first into the macaroni tubing and then force it up and out of the macaroni tubing and to the sales line. An optional plunger may be used to help reduce paraffin or scale buildup in the macaroni tubing.

Title: Improved apparatus for sensing fluid flow and associated load control circuit
Inventor: MCHUGH GEORGE J
IPC: A62C35/60
Filed: 1999-12-20
Abstract: A circuit and apparatus for magnetically sensing fluid flow and applying voltage to a load. A valve disposed within a conduit is provided with a magnetic shield. A magnet is located on one side of the magnetic shield while a sensor, associated with the valve is located on the opposite side of the magnetic shield. The valve, and hence the magnetic shield, moves to permit fluid flow. When the magnetic shield moves due to fluid flow, the magnet activates the sensor. A load control circuit includes a supply terminal for receiving a supply voltage and a detector which detects a condition requiring the operation of a load. The detector causes a threshold voltage to be generated from the supply voltage, and a time delay controller controls the time required to generate the threshold voltage. A DIAC or equivalent element conducts to generate a first trigger signal once the threshold voltage is achieved, and a silicon-controlled rectifier (SCR) generates a second trigger signal in response to the first trigger signal. The circuit includes an opto-TRIAC and triac which are rendered conductive by the second trigger signal to cause a voltage to be provided to the load.
